UPDATE: The storm is now subsiding, having never reached G2 level. However, auroras remain possible at high latitudes.
A CME struck the Earth’s magnetosphere earlier today, triggering a G1 geomagnetic storm, which is mild but enough to create auroral displays in Arctic countries. A second one emerging from the same sunspot group is still coming, and NOAA is predicting a 75% chance of a G2 class storm, which is considered moderate. This could trigger some disruptions in service at high latitudes, but mostly will trigger more auroras — possibly as far south as the 45th parallel. So if weather permits and you’re up late, take a peek to the north. 😉 Or at least check spaceweather.com for live updates on conditions.
